OIL-SEPABATUR.

Application filed. March 6, 1915.

To all whom it may concern:

Be it known that 1, JOHN Evo, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Oil-Separators, of which the following is a specification.

This invention relates to oil separators and is especially designed for separating oil from the water of condensation from steam boilers.

The object of the invention is to provide a simple and eflicient device which will effectually separate the oil from the water of condensation from steam engines so that the oil may be recovered and the condensed water returned to the boiler free of oil. In this manner the oil may be used over and over again.

Another object of the invention is to provide a. device of this character having means for preventing agitation of the water of condensation by the incoming steaming water and to filter all water returned to the boiler feed pump so that every particle of oil carried off by the steam will be eifectively removed from the water of condensation prior to being returned to the boiler and no water will gain access to the oil outlet.

Still another object of the invention is to provide a device of this character having an adjustable skimmer which may be properly regulated according to the water level in the tank.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawing, which forms a part of this application and in which Figure 1 is a side elevation, Fig. 2 is a top plan view with the lid removed, Fig. 3 is a detail sectional view taken on the line 33 of Fig. 2, Fig. 4 is a sectional view on the line 4-4 of Fig. 2, and Fig. 5 is a detail sectional view taken on the line 5--5 of Fig. 2 looking in the direction of the arrow.

Referring more particularly to the draw ing, 1 represents a tank of any suitable shape and capacity which is provided with an inlet pipe 2 and which is divided into separate compartments 3 and 4 by a vertical partition 5 which extends the full height of the tank and is made water-tight at the bottom and sides in any suitable manner. In the compartment 4 there is secured to the wall of the tank a U-shaped guard 6 which cov- Specification of Letters Patent.

ers the outlet pipe 7, as shown, so that should any oil accidentally get into the compartment 4 it will be prevented from gaining access to the outlet pipe 7 owing to the fact that the guard 6 extends to a point adjacent the bottom of the tank to a point adjacent the top thereof, as is shown in Fig. 4, and the entrance to the channel formed by the guard being below the opening 8 which forms communication between the compartments 3 and 4.

The inlet pipe 2 enters the tank at approximately the same level as the outlet pipe but has its inner end covered by a shield 9 whose lower end is extended below the pipe 2 whereby the water will be deflected downwardly upon the filtering box. This causes the liquid to be thoroughly fi1- tered, the force of liquid being directed upon the filtering material and forcing itself through the material into the next compartment.

Secured to the partition 5 within the compartment 3 are guiding cleats 10 which are engaged by the lateral webs 11 of a perforated box 12 arranged to contain charcoal or other similar filtering material and having an opening 13 in register with the opening 8 in the partition This box effectually cuts oif direct communication between the compartments 3 and 4 and causes all the water passing from the compartment 3 to the compartment 4 to pass through the charcoal in the box 12 and thus be relieved of any oil held in suspension by the water.

Any oil floating upon the water will be removed by a skimmer 14 in the form of a funnel and having an extension pipe 15 depending therefrom and telescoping within the vertical portion 16 of the outlet pipe 17. This outlet pipe may be connected to any lubricant container and with its extension 16 is stationary, the skimmer and its extension 15 sliding therein and being held at the proper height in the compartment 3 by means of a supporting rack 18 which is slidably mounted in the bracket 19 carried by the tank 1 and held in adjusted position by means of the pivoted dog 20 carried upon the bracket 21. Each compartment'is provided with a capped pipe nipple 22 by which access may be had to the interior of the tank for cleaning purposes.

That is claimed is An oil separator comprising a tank, a partition in said tank dividing the same into adjacent the inner end of said inlet pipe, an outlet pipe formed in said tank adjacent the top thereof and a guard disposed above the inner end of said outlet pipe.

In testimony whereof I afiix my signature in presence of two witnesses.
